Locomotive turbine conversion?

Have you ever taken a car and fitted a much larger engine to it?

Read up.Before that 2.8 V6, engine vas 1.6 4-cyl.

OK, good then. A lot of times people ask questions like this and don't
really have the slightest idea what they're getting into. Clearly you
have a little more experience.

Have you ever worked with turbine engines before? (Obviously not, based
on your questions)

No.I prefer NA engines.Even now.I'm interested in turbines as engines, not
like add on to piston engines.

Yeah, I know, I mean "gas turbine engines," not turbo/supecharged
engines.

In order to succeed, you first need to turn your turbochargers into a
turbine engine. Before you can even begin to think about doing this you
need to learn how turbines work. Then you can begin laying out a plan.

I know principles, after all, I'm studying railway traffic, and we have many
mechanical courses.

Well, when you asked, "what is a compressor," I wondered. That is like
asking a piston mechanic, "what is a cylinder?"

This is a project that would probably keep you busy for 5 years if you
work part-time.

You mean on locomotive turbine into car, or just plain turbocharger
converting to gas turbine?If is this last, then you must se what people on
intrent have made for month or less with scrap turbocharges from local
junkyard.

Are they generating useful power, or just making a lot of noise? Making
noise is easy, making power takes engineering skill. That's what will
take you time. Are they skilled mechanics doing their second or third
project, or a first-time experimenter just like you? I'll bet the
second time you do this, you will do it a lot faster than the first.

As for how much power it puts out, who knows? There's a ton of
variables in there. I'd suspect a few hundred horsepower, maybe more,
quite likely less. It will probably turn out heavier than an equivalent
piston engine, and thus the car will actually go slower.

Why?That doesn't mean that it must be like you said.

Well, let's look at it this way. Teams of engineers, with literally
billions of dollars to spend, build turbines that put out maybe 800
horsepower (and of course a lot larger too). Of course, you don't have
to worry about safety or reliability, so your job is easier that way,
but you're also working with inferior materials and knowledge (not
meant as criticism, just fact).

You may be able to get 500, 700, 1000HP out of a turbine but my guess
is that your turbine will end up weighing a LOT. Weight is not the
first concern when building parts that go on locomotives- durability
and low maintenance cost matter a lot more. The result is that heavier,
cheaper materials are used and often overbuilt (adding more weight).

Weight is your enemy. If my car has the same power as yours, and mine
is heavier, then your will be faster. Simple physics.

How cool will
that be?

Why that tone?I mean, what is so wrong if I ask something like this

Sorry, I'm not trying to be discouraging, just realistic. If you think
you can build a turbine in a few months that will make your car go
super-fast, you're probably going to be disappointed. If you're ready
to spend a couple of years in the shop, building, testing, fixing,
building, fixing, testing, then you just may be able to get something
pretty cool.

Hey, really, I wish you the best of luck. I hope it works.

Best,

Yes, its been done with the turbo's for road vehicles

Hmm...That text is little bit confusing, in fact I don't really understand
what are they talking about...They have said much, but still, nothing.Only
some story from that race.

Sure BUT it would be a very complex build as you'd need to build a
compressor stage and burner cans and then couple the
high revving turbine to the transmission.

I know.High revs can be solved with reductor.Now, I need more information
about compressor stage and burner cans

Then visit a library


I presume that all this could fit to a car, for example Ford Cortina, or
something like that.

Its been done so its possible.

How strong must be, I mean how much thrust could turbocharger from car
produce?Could I make a one man vehicle from that?


Thrust is meaningless unless you intend making a jet powered car.

Given enough time and money you can build anything and gas turbine cars
have been built. The real question is why ?

I know that gas turbine cars have been built, but the real question is,
have
they been built in private garages?
Why?
Why do people climb on mountains, why do people surf, why do people like
diving..?
I hope you understand what am I aiming for.I want to have a first gas
turbine powered car in Croatia. Is that enough?

No

Jet powered streetrace car...Hmm...Nice... ( like Homer Simpson would
said )



First learn a little about engineering


Such a vehicle is likely to be unreliable and extremely inefficient in
using fuel and probably could not be certified for road use.

That isn't my intention at all.I want to make that car, not for daily use,
but for streetrace, for example, why not?That would be a show...


And almost certainly illegal.

A better approach may be a hybrid using a small gas turbine running
at constant speed to charge a battery for an electrically driven
vehicle.

If I wanted to do that, I would go on some 1.4 liter diesel engine, which
can I buy almost everywhere and make electric car.



Indeed

Yes, I know, mea culpa, I mixed some things.My intention is to make traction
car, not thrust.

No

Why not?

First learn a little about engineering

Like I said post before, I know mechanical engineering, but I haven't never
been interested in turbines.I'm working all by myself on my car.Ask me
anything about piston engines and I'll tell you.

And almost certainly illegal.

Look, I don't know where you from, but trust me, it's legal, here it is.I
don't know for you and your country.

Indeed

Yes?

Wow, Anton. I'm impressed! You were a lot more polite than most people would
be after receiving such a snotty, rude reply.

Good luck in your project.

The UK's APT (Advanced Passenger Train) of the 1970s used 6 gas
turbines to power it. Never made it into service.

That was only the experimental version, the prototype and production
versions
were intended to be electrically hauled. The BoBo power car design was used
to build a new locomotive, the Class 91 capable of 140mph, which pulls the
Inter City 225 on the East Coast main line today.

You're right - but it was still the nicest of the APTs! would look
state of the art, even today.The protype had a few things batting
against it - one of which was that the turbines were built by Leyland
....this was around the same time they were churning out
Princesses/Ambassadors and Allegros...
